The couple, who has been relatively private about the relationship, is believed to have been dating for a few months. It was only last month in a birthday post for Schwarzenegger that Pratt confirmed the relationship publicly.

Pratt, who was raised in Lake Stevens, has made a name for himself in Hollywood, helming the "Jurassic Park" franchise, as well as staring in "Guardians of the Galaxy." He was previously married to Anna Faris, whose family is from Edmonds and attended the University of Washington. The couple announced their separation in August 2017 and said in October 2018 that their divorce had been finalized.

Schwarzenegger, as the name might suggest, is the daughter of actor and former California Gov. Arnold Schwarzegegger and broadcast journalist Maria Shriver. She has written several books, including "I Just Graduated ... Now What?"

In the announcement on his Instagram, Pratt said he was "thrilled to be marrying" Schwarzegger and "proud to live boldly in faith with" her.
